POLISH international Grzegorz Krychowiak joined Albion in August on a season-long loan move from Paris Saint German.
The midfielder, who can also play in defence, began his senior career in France with Bordeaux after initially playing youth football in his native country.
He made his Poland debut in December 2008 during a friendly against Serbia and has gone on to represent his nation over 40 times, including an impressive showing at Euro 2016.
Krychowiak spent two seasons out on loan with Reims from 2009-2011, helping them to promotion to the French second tier in the 2009/10 campaign and playing a crucial role in their mid-table finish in Ligue 2 the next year.
He then went out on loan at another Ligue 2 team, Nantes, for most of the 2011/12 season before going back to Reims to sign permanently the following summer.
After making 70 league appearances for Reims across two seasons, he then secured a move to Spanish side Sevilla in August 2014.
The 27-year-old won back-to-back Europa League titles at Sevilla, scoring in the 2015 final win over Dnipro and playing an important part a year later as they lifted the trophy at the expense of Liverpool.
This earned him a move to French giants PSG, where he was part of the squad that won the Trophee des Champions, Coupe de la Ligue, Coupe de France and finished second in the league last season.
